Do not have regexp support for metricAnnotationsAllowList

[chownx1]

What would you like to be added:

Support wildcard or regex matching in --metric-annotations-allowlist, for example:

• pods=[monitoring.vmagent.io/*]
• pods=[^monitoring\.vmagent\.io/.*$]

Why is this needed:

Many annotation keys share a common prefix, but today they must be listed one by one. This is hard to maintain and does not work well for dynamic annotation names.

Describe the solution you'd like:

Allow filtering annotation keys by prefix or regex in --metric-annotations-allowlist, while keeping support for exact matches.
